Answer:
2.5 is a rational number which is not an integer. A rational number is a number which can be written as a ratio of two whole numbers (integers). For example 5 is a rational number since 5 can be written as ratio of 5 : 1 . 5 is also an integer.
Answer:
24
Step-by-step explanation:
X + (X + 2) = 50
2X = 50 - 2
2X = 48
X = 24
The proportional relationship involving c and b is c ∝ b. The solution to c is c = kb (where k is constant)
Variation is a mathematical notion that relates to variability. Variation is defined to be any change in one quantity as a result of a change in another. Variation questions feature relatively basic connections or formulae in which one variable equals one term.
From the given question
- if c represents the number of calories, and
- b represents the number of brownies.
A direct variation is a type of variation in which an increase in one term increases the other term as well, and, vice versa.
Let assume the proportional relationship follows a direct variation.
Then,
c ∝ b
The solution to c is:
c = kb
(where k is the constant)

Candice bought 1,008 beads. I found the answer by adding how many packages she bought all together ( 4 + 9 + 6 + 2 = 21 ) and then multiplied 48 by 21. :) Hope this helps.
